Abstract: 181,708. Geuns, J. E. C. van. June 14, 1921, [Convention date]. Void [Published under Sect. 91 of the Act]. Lantern shutters.-An anti-dazzle device for motor and other lamps of high illuminating power consists of a frame supporting a number of thin parallel plates spaced at small. distances from each other and situated in front of the lamp so that only inconvenient rays are intercepted. The frame may be fixed to the lamp and the plates moved in groups carried by separate frames, or the frame as a whole may be mounted so that it can be rotated through 25‹. The plates which may be made of glass, metal, paper, fabric, &c. are each 50 mm. in width and are spaced 2¢ mm. apart and have their lower sides made reflective, and their upper sides dull black or tinted so as to become brighter or darker from the front to the back. Glass plates may be mounted at the front and back of the frame to prevent entry of dust, water, &c. The plates, which are normally mounted in a horizontal position, may in some cases be arranged vertically; they may also be given a bent or broken shape.
Patent GB-389101-A (GB)
Title: Improvements in and relating to the recording of sound
IPC: G11B7/00
Filed: 1931-06-04
Abstract: 389,101. Cathode-ray tubes; photoelectric cells. HERD, J. F. and LUTKIN, F. E., Radio Research Station, Slough, Buckinghamshire. June 4, 1931, No. 16247. [Class 39 (i).] Sounds are recorded optically by means of a cathode-ray oscillograph in which the beam of electrons is influenced by voltages of supersonic frequency to form on the fluorescent screen a line whose position or intensity is then varied in accordance with the sounds to be recorded. An electron beam from a cathode 1, as shown in the Figure, of a cathode-ray oscillograph is projected through an aperture in an anode 2 and is focused to produce a spot of light upon a fluorescent screen 3. After leaving the anode 2, the beam may be deflected electrostatically by electrodes 4, or by means of current-carrying coils outside or inside the tube, or by a combination of such means. The electron beam is accelerated by a further anode 2A to produce a more intense response on the fluorescent screen. The beam of electrons, where incident upon the fluorescent screen, is drawn out into a line by means of a supersonic frequency voltage and the width of the line is then varied by modulation of the supersonic voltage by the audio-frequency voltage derived from the microphone. Alternatively, the electron beam may be vibrated by a voltage of supersonic frequency to produce a luminous line which is then vibrated along its own length by applying to the oscillograph the voltages from the microphone. For recording a variable density record, the audio-frequency voltages may be applied to produce variations of intensity of the luminous line on the fluorescent screen. Specification 235,254, [Class 37, Electricity, Measuring &c.], is referred to. The Provisional Specification describes also the recording of sound by a cathode-ray oscillograph wherein a vibrating spot of light is produced on the fluorescent screen and is photographed as a sinuous,trace on the record film. Such a record may be reproduced by a photo-electric cell in which the emissive cathode is formed as a narrow strip and the anode is plate-shaped and positioned so that the current variations between it and the cathode are proportional to the amplitude of movement of the reproducing spot of light. The law of variation of the current may be arranged, by so shaping and positioning the cathode, that correction is made for distortion in the recording and reproducing systems. According to a modification, the anode may be in the form of a plate or plates with an interposed grid between it and the cathode, which grid serves to vary the law of conductance according to the position of the spot of light on the cathode. The grid may be a current-carrying wire, or an equipotential grid, the mesh of which is varied along its length, or the distance from the grid to the cathode may be varied along its length.

Title: Improvements in or relating to joints between austenitic steel tubes or pipes and ferritic steel tubes or other elements
Inventor: WEBB THOMAS BASIL
IPC: B23K9/028
Filed: 1950-06-29
Abstract: 706,015. Uniting by fusion. BABCOCK & WILCOX, Ltd. June 25, 1951 [June 29, 1950], No. 16259/50. Class 83 (4). [Also in Group XXVIII] In joining a tube of austenitic steel to an element of ferritic steel, a transition piece is formed by butt welding end to end lengths of pipe respectively of austenitic and ferritic steel and machining the inside of the piece to remove material from the weld root and welding end to end the tube and pipe length of austenitic steel and connecting the element and pipe length of ferritic steel. A transition piece 3, Fig. 1, is formed by depositing weld metal 8 in a groove between the chamfered ends of a short austenitic steel pipe 4 and short ferritic steel pipe 5 respectively. After welding and heat treating, e.g. normalizing, the piece 3 is machined to the size of the pipes to be joined internally to the line 9 and externally to the line 10 and the ends of the piece 3 are chamfered at 15, 16. The weld 8 may be non -destructively tested. The austenitic pipe 4 is then welded at 17, Fig. 2, to an austenitic steel pipe 1 of approximately the same composition and the ferritic pipe 5 is welded at 18 to a ferritic steel pipe 2 of approximately the same composition. A suitable austenitic steel comprises 18 per cent chrome and 8-12 per cent nickel while a ferritic steel may contain ¢ per cent molybdenum or 1 per cent chromium. Superheater tubes of austenitic steel which are subjected to high external gas temperatures are joined to superheater tubes of ferritic steel subjected to lower temperatures by a joint as in Fig. 2 described above which is located out of contact with the hot gases. The transition piece may be welded to both tubes on site or to one tube in the factory and one on site. Each austenitic superheater tube is joined by a transition piece to a ferritic tube which is rolled into an outlet header. In a further embodiment an austenitic steel tube 31, Fig. 5, is welded to the austenitic pipe 34 of a transition piece 33 while the ferritic pipe 35 thereof is expanded into a ferritic steel header 32 and seal welded thereto at 51. In a modification the pipe 35 of the transition piece 33 is welded directly to the header 32. According to the Provisional Specification the diameter of the transition piece adjacent the weld uniting them may be greater than that at the ends and further the pipe length material may be more costly than that of the adjacent tube.

Spray carburettors.-A multiple jet carburettor comprises two parallel rows of small choke tubes 1 - - 5 each provided with a fuel nozzle e, the pair of choke tubes 1 being permanently open to the body a which is connected at a<1> to the induction pipe, and the remaining pairs of choke tubes being brought into action in succession by a valve comprising a pedal-operated plug f on which is mounted a sleeve g. The plug f and sleeve g are provided respectively with ports i, k, and the sleeve g is slidable on the plug f, its movement being limited by a stop l and a shoulder o. As the valve is opened, the plug f first moves relatively to the sleeve g and the ports i, k are brought into alignment, thus bringing the choke tubes 2 into action. The two parts of the valve then move together, each pair of choke tubes starting to come into action through the ports i, k before the end of the valve has completely uncovered the outlets of the preceding pair of choke tubes. The fuel is lifted from a low level tank by suction and passes to a series of fuel pipes c, each of which is provided with a filter d and supplies a pair of nozzles e.

Angular bending; twisting wires together. -In a machine for securing the end coil 4 of an upholstery spring to the adjacent coil 5, the end 7 of the spring is bent at about 90‹ by the forward movement of a casing 9, 14 which carries a twisting pinion 10 and surrounds cams 15<1>, 15 on a, driving shaft 1 which swing it about an axis 13 parallel with the shaft, until the pinion engages the end, whereupon the end is coiled round the adjacent coil, and the casing then swung back by the cams. The pinion is rotated by a gapped wheel 18 and is locked by a cam-operated rocking lever 20 after coiling has been effected. The bending is effected by a groove 8 on the part 9 which forms the cover of the casing 14. The rocking lever 20 is mounted on the axis 13 and is normally pressed by a spring 21 against a stop 23 on the casing so that its stud 19 engages and locks the pinion. Just prior to the engagement of the wheel 18 with the pinion 10, the rocking lever is disengaged from the pinion by a cam 24. The spring is mounted on a fixed table 6 and the two end coils held in place by a clip 2.
